This thoughtful, reflective evolution of the previous edition rethinks how leadership has evolved over the past ten years. It focuses on three key ideas: the concept of layered leadership, shared experiences in making meaning together, and the importance of rowing in the same direction as a school community. The book declares that teachers already know what they need when it comes to professional development, and describes the layers of support that coaches can implement within a school, including in-class support, curriculum support and assessment, study group facilitation, and the cultivation of teacher leadership.
